  • Meanwhile, in an oven-safe bowl or stackable steamer, insert pans add 3 cups of pasta with 3 cups of water, and keep aside. Make sure pasta should be submerged in liquid.

  • Add some minced garlic and onion saute till turn translucent.
  • Then add the squash, salt, and water, cook until completely tender. Place the squash mixture into the blender along with some salt and pepper and pulse until smooth.
  • Pour the sauce over the cooked pasta and add the cheese. Stir until melted. Add more salt and pepper to taste.

I have prepared this dish in my electric pressure cooker, Instant Pot DUO60 6 QT.


  • Pasta cooking time: The time to cook pasta in an Instant pot is usually half of the suggested time on the pasta box minus 1 minute for al-dente pasta ( if you like your pasta firm and are just done). For example, I made this recipe using a dry shell which called for 10 minutes of cooking time. That makes it 4 minutes going by the rule of thumb.
  • Keep pasta submerged: You have to make sure that all the pasta is submerged in the liquid before pressure cooking. If it is less, then add some more water or broth
  • Pressure Release: Quick Release is very important for cooking pasta in the Instant Pot. So don’t forget else it will result in very soft pasta.
  • Seasoning: I have used dried Italian herbs for seasoning but you could use freshly chopped parsley or sage.


  • Adding milk while pureeing butternut squash sauce is completely optional.
  • You can also add steamed broccoli florets in this pasta, in the end, to make it more healthy and delicious.
  • You can also use frozen butternut squash for this recipe.
  • This pasta can also be made using roasted butternut squash.
